[Brother Seamus]

I am trying to build the neccesary files for the stevens/rago APUE.2e book on FreeBSD 7.0

as instructed i get the source from here: http://www.apuebook.com/src.tar.gz

unzip & untar to:

/home/seamus/apue.2e

cd /home/seamus/apue.2e

amend "Make.defines.freebsd" as instructed so:
"WKDIR=/home/seamus/apue.2e"

and then run "make" from this directory.

I get the following error:
+++++++++++++++++++++++++++++++++++++++++
pracct.c  ../lib/libapue.a 
pracct.c: In function 'main':
pracct.c:31: error: storage size of 'acdata' isn't known
pracct.c:31: warning: unused variable 'acdata'
*** Error code 1

Stop in /usr/home/seamus/apue.2e/proc.
*** Error code 1

Stop in /usr/home/seamus/apue.2e.
*** Error code 1

Stop in /usr/home/seamus/apue.2e.

I would appreciate any help.
